IEANY, or BROOKLYN, NEW.YORK, A CORPORATION or new YORK TEMPORARY BOOK OF SHEETS Application filed J'uly 21, 1923. gel-a1 No. 2514, 454.

This invention relates to temporary books of sheets and more particularly to tablets, e., pads or'blocks, of printed loose leaf forms. t is one of the objects of this invention to eliminate wastage in the handling of printed forms. Another object of the invention is to provide the sheets in a temporary tablet or book form which will open like a bound book, permitting entries to be made on the sheets until such time as they are ready I to be torn out and put in the'loose leaf binder.

In the drawings: i

Fig. 1 is a plan view of a book of sheets made according to this invention;

Fig.2 is a side elevation'of the book with the cover opened out; and

Fig. 3 is an enlarged and'exaggerated elevation of the ends of the sheets showing their stepped or overlapped relation, and

Figs. 4 and 5'illustrate a method of making a book according to my invention.

Books of account and other clerical records are nowadays generally kept in loose leaf form and sheets have to be added to the various books or binders from day to day. The supply of blank printed forms both in the retail store and'the ofiice is generally kept in such manner that each sheet is separatefrom the other and considerable wastage occurs. Furthermore, there is no satisfactory way of keeping the partially completed sheets together until they are ready to be put into the binder. According to. this invention the printed forms are provided in a tablet of sheets fanned" out or shingled until the ends ofthe sheets are in a stepped or overlapped relation, Thus in thedrawings the sheets 5 have been offset with the top sheet overhang ing the sheet below at oneend and the re- 4 maining sheets similarly overlapped. I prefer to makethe amount of the overlap substantially more than the thickness of the sheets. Thus for instance with a sheet of the thickness which might be used in account- I mg work, the sheets may be overlapped or offset to eXposea portion of the face of each sheet about 1/52 of an inch wide. These sheets mayof course be produced with any type of perforations, such as the notches shown at 6 in Fig. 1, to enable them to be put directly in the loose leaf binder when they are removed from the temporary book. It will be obvious that if desired groups of two or three sheets can be kept in register and offset as a group; Since the printed forms for loose leaf work are generally of the same size,

it will be obvious that the free edges of the sheets in the, book will also overlap each of the sheet s'hinged below it, thus making it easy to grasp the desiredsheet. I r

For the purpose of fastening the sheets together in this temporary book or tablet thin flexible paper or other thin or frail material such for instance as Japanese tissue can -be laid over one end of the tablet in strips? as backing. This thin paper is laid in contact with'what might be termed treads 9 formed by the overlapping and risers Swhich are the thickness of the sheets as shownin Figs. 2

and 3. This feature of having the tissue lying in the steps in direct contact with'the eX- posed facesand ends of the sheets is of primary importance. ;Theflexible paper is caused to adhere to the/sheets by a gum or other adhesive lO which is spread on the exposed ends-and faces of the sheets as shown in Fig. 1 where one corner of a strip 6 has been turned back. The. adhesive should be thin enoughto permitthe thin paper to follow directly, the treads andrisers, andrprefer- 8o ably should itself be flexible. I prefer to attach thes heetstogether in the following manner. I take. the desired number of sheets and stack them in exact register with'eachother, as usual, asshown in Fig. 4 at 20. The stack-ofsheets is clamped be-" tween rounded blocks 15 and'16 of equal heightQ-f' r I The stack is then flexed about block 15 as shown in Fig. 1 at 30, which fans out theend of the sheets in a stepped relation. Then the adhesive is spread upon the sheets as shown at 10?. If desired the back may be applied at this point. However, I prefer to flex the stack of sheets at this point over the other block 16, as shown in Fig. at 40. The amount of overlap between sheets is the same at 40 as at 30, but the relation of the sheets has been inverted, the sheets which hadthe position 5 and 5 in Fig. 4 now having the respective positions of 5 and 5 in Fig. 5. Adhesive is again applied at 10, to which the backing 7 is applied. This method is an easy way of securing the desired amount of overlap between the sheets. 7 If two applications of adhesive are 'made as described above,

there is, in addition to the layer 10 of adglued on the coverll outside the backing.

f tablet, entries can be written thereon without hesive between the backing and thetread and riser of each sheet, a small amount of adhesive (10 of Fig. 5 between the under side of the tread portion of each sheet and the sheetv below it. This strengthens the hinge between the sheets. The backing 7 may be turned under and glued to the back cover 11 of tablet, and a hinge 12 for the cover may be removing it from the tablet and if it is desired to write on the reverse side or back of the tablet the sheet will lie flat when turned over. I have-discovered that with the backing adhering directly to the face of the sheets as described, the sheets will open'out flat as in a bound book without separating from each other and without'bowing up as in a holder where the sheets are clamped together. How- 7 ever, it does not require much strength to pull asheet loose from the temporary book and I have observed that this pull takes place without leaving any portion of the sheet attached to the remainder ofthe book. In av similar manner the'temporary book can be opened at any pointand the sheets will lie flat without detaching them from the book, thus making it possible to make entries on any sheets in the :temporary book without destroying the tablet. The advantage of a construction which can be used in this manner will be obvious and it-is believed thatthi'siis the first time that loose leaf formshave been provided in a temporary book-or tablet form where-they can be openedout flat and written on without destroying the temporary grouping and yetthe sheets can be removed from the'temporary book in the same manner as from an ordinary pad of paper.

What I claim is:

1. A temporary book comprising a plurality of sheets with the ends of the sheets in stepped relation, in combination with a back ing adhering to and following the surfaces together, said book being adapted to permit removal of the sheets.

3. A temporary bookcomprising a plurality of sheets with the ends of each sheet in stepped relation to the adjacent sheet, in combination with a thin layer of adhesive on the ends and faces of the sheets exposed by the stepped relation and thin paper on, and ad hering to said faces sheets together. 7 7

4. A temporary book of loose leaf forms comprising a plurality of sheets with the ends of the sheets in overlapped. relation in combination with thin paper lying in the steps thus formed at one edge of the book and joining the sheets together.

and ends hinging the n n 5. A temporary book of loose leaf. forms comprising a plurality of sheets each overlapped with relation to the adjacent sheet, in

combination with a thin layer of adhesive-on the treads and risers formed by said over lapping and a backing following and adhering to said treads and risers hing-ing the sheets together. V 7

6. Ate'mporary book of loose leaf forms comprising a plurality of sheets with each sheet offset from the adjacent sheet substantially more than the thickness of the sheet, in

combination with frail flexible sheet material I lying in the steps formed by the offsetting and joining the sheets together. 7 I I 7. A temporary book of perforated loose leaf forms comprising a plurality of-sheets with the end of each sheet in stepped or overlapped relation to the adjacent sheet a distance substantially more than the thickness of the sheet, in combination with a thin layer posed at one end ofthe book and thin paper following the steps and adhering to the faces of the sheets and hinging same together.

A temporary b ook comprisinga plurality of sheets with the end of each sheet in stepped relation to the adjacent sheet, in com-i bination with alayer of adhesive on the treads and risers formed by the stepped ends of the sheets and a thin layer of adhesivebetween theunder side of the tread portion of each r sheet and the sheet below it.

9. A method of making a temporary book comprising clamping a stack of sheets between two rounded blocks of equal height, the sheets being in register, flexing the stack about one block so that said ends of the sheets are in stepped relation to each other, spreading adhesive upon the treads and risers of said ends, flexing the stack about the other block so that said ends are in inverse stepped relation to each other, spreading adhesive upon the treads and risers thus formed and applying a backing.
